What makes you think you're putting out less power? Certainly fit can affect power but I'm curious how you are comparing. I presume you don't have a powermeter so in lieu of an objective measurement of power do you at least have an HRM? Is your HR lower on the road bike? It's possible you're putting out more power on the road bike and that's why your legs feel tired.
The other significant difference between road bike riding and MTB is that you tend to get much steadier efforts on the road bike. Depending on where you're riding there are usually a lot more breaks or changes of pace on a MTB whereas with a road bike you can easlly ride steadily for 20-60 min. If you aren't used to a steady unbroken effort that may feel different as well.
